Remember, our system is a great improvement over traditional woodwind fingering charts. It is durable, easy to use, versatile and it eliminates fumbling across multiple sheets and books to find a note. This tool provides an unambiguous and large view of the finger stations in a smaller form factor than a conventional chart can. This translates to better readability under any conditions.

The unique rotary design of dxdt's rotary wind instrument fingering chart system makes it ideally suited for use as a key transposition aid. Simply aim the main pointer to the key of the piece you wish to transpose and place a piece of tape or an erasable mark on your destination key.

Now whenever the main pointer is directed to a note in your piece to be transposed, the transposed note will be pointed to by the temporary marker. If you would like to transpose a piece written for an instrument into concert pitch, there are instructions given in a .pdf at the bottom of this page.

This tool is ideal for beginning and intermediate students as well as teachers. Professional musicians that double on other instruments have also purchased them as a compact and handy resource.
